Description

Technical Field

[0001] The utility model belongs to the field of optics, and relates to a mirror attitude adjustment device, in particular to an electrically driven mirror attitude adjustment device. Background Technique

[0002] Mirrors are commonly used in the field of optical technology, and their main function is to reflect light beams so as to achieve the transmission of light beams in the required direction in space. In actual applications, due to errors caused by aspects such as optical path calculation, machining technology, and assembly technology, there are certain deviations in the installation of the mirror. Mirrors at key positions need to be adjusted as necessary to compensate for the impact of this deviation on the optical system. Generally, it is necessary to finely adjust the spatial attitude of the mirror, including pitch and yaw adjustments.

[0003] For example, in the utility model patent with the authorization announcement number CN219997394U, a mirror adjustment device and an adjustable mirror device are disclosed. It mainly forms a relatively stable support surface through the positioning surfaces of four positioning screws, and can quickly reset the position of the mirror and re-adjust it by cooperating with the reference surface of the mirror base, and can quickly adjust the mirror to the optimal state position, thereby improving production efficiency. Another example is the invention application with the publication number CN117233919A, which discloses a mirror holder, including a fixed structure, a movable structure, and a tension spring connecting the fixed structure and the movable structure; the fixed structure includes a first base and a first rod arranged on the first base; the movable structure includes a second base, and the first rod is supported on the second base; there are two first surfaces and second surfaces at an angle to each other on the second base, and both the first surface and the second surface are in arc surface fit with the first rod; alternatively, a load-bearing rod parallel to the first rod is further arranged on the first base, the first surface is in arc surface fit with the first rod, and the second surface is in arc surface fit with the load-bearing rod.

[0004] It is not difficult to find that the technical contents disclosed in CN219997394U and CN117233919A can adjust the attitude of the mirror, but there are still the following deficiencies: 1) The attitudes of the mirrors rely on manual rotation of adjustment screws to implement attitude table adjustment, which cannot meet the requirements of electrified and automated optical path adjustment scenarios, and the degree of automation is not high; at the same time, due to manual operation, the stability is poor; 2) It does not support electrically driven attitude adjustment, cannot support efficient electrification and automation of the optical path, and is not convenient to use; 3) It lacks installation interfaces for actual use and cannot be directly applied to engineering systems.

[0029] See Figure 2, the mirror base attitude adjustment mechanism adopted by the present utility model includes a first piezoelectric screw 11; the first piezoelectric screw 11 penetrates through the mirror base 2 along the thickness direction of the mirror base 2 and is fixedly connected to the mirror base 2; the first piezoelectric screw 11 drives the mirror 10 to adjust its attitude through the mirror base 2. At the same time, in order to position the first piezoelectric screw 11, the mirror attitude adjustment device provided by the present utility model further includes a planar positioning block 8 arranged on the mirror support 1; the first piezoelectric screw 11 abuts against the planar positioning block 8 after penetrating through the mirror base 2.

[0030] Continue to refer to Figure 2 , the mirror attitude adjustment device provided by the present utility model further includes a positioning mechanism, and the positioning mechanism includes a groove positioning block 4 arranged on the mirror support 1 and a spherical positioning block 5 arranged on the mirror base 2; the spherical positioning block 5 is in spherical cooperation with the groove positioning block 4.

[0031] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the mirror support 1 adopted by the present utility model is an isosceles right triangular prism, and the mirror support 1 includes a bottom surface 101, a 45° inclined surface 102, and a side surface 103; the mirror base 2 is arranged on the 45° inclined surface 102 through a pressing mechanism; the light-transmitting hole is arranged on the side surface 103 and is on the optical path of the incident light incident on the mirror 10 and on the optical path of the reflected light reflected by the mirror 10. Among them, refer to Figure 1 , Figure 2 and Figure 5, both the bottom surface 101 and the side surface 103 are provided with a plurality of threaded holes. Exemplarily, 3 threaded holes are reserved on the bottom surface 101, and 4 threaded holes are reserved on the side surface 103 (the structures of the two side surfaces are exactly the same). The hole sizes and spacings on each surface are the same, which can meet the installation requirements of different usage scenarios. The light-transmitting holes are one or more. When there are multiple light-transmitting holes, the multiple light-transmitting holes are respectively arranged on different side surfaces 103. Taking Figure 3 as an example, there are two light-transmitting holes, which are respectively arranged on different side surfaces 103. The two light-transmitting holes (one on the Figure 3 right side surface 103, and the other on the Figure 3 bottom side surface 103) are perpendicular to each other in the axial direction. At this time, the beam to be adjusted is incident from the Figure 3 right side light-transmitting hole to the reflector 10, and after being driven by the first piezoelectric screw 11 and the second piezoelectric screw 13, the mirror base 2 drives the reflector 10 to adjust its posture, and then reflects the incident light to form a reflected light, and the reflected light exits from the Figure 3 bottom light-transmitting hole.

Exemplarily, 4 groups of shoulder screws 6 can be used. The 4 groups of shoulder screws 6 sequentially pass through the compression spring 12, the gasket 7, and the mirror base 2, and finally are threadedly connected to the reflector bracket 1. Since the shoulder screw 6 and the compression spring 12 are connected to the reflector bracket 1 through the mirror base 2, the elastic force of the compression spring 12 makes the mirror base 2 and the reflector bracket 1 tend to approach each other. At this time, the spherical positioning block 5 and the groove positioning block 4 form a support point B that can freely rotate in space through spherical cooperation; wherein the second piezoelectric screw 13 contacts the plane positioning block 8 to form a support point C that can freely slide at the end of the plane positioning block 8; the first piezoelectric screw 11 contacts the V-shaped positioning block 3 to form a support point A that can slide along the V-groove at the end of the V-shaped positioning block 3. The first piezoelectric screw 11 and the second piezoelectric screw 13 change the protruding amount of the screw head through an electric drive form, so as to drive the mirror base 2 to deflect and realize the posture adjustment of the reflector 10. The reflector bracket 1 and the mirror base 2 are connected by four groups of compression springs 12, and compared with the traditional tension spring, the stability is better.
